Why is Mimosa shy?

1. Reasons

1. Mimosa is different from other plants. It has pulvinus growing at the base of its leaves and petioles, and the distribution of parenchyma cells in the pulvinus is also different. When people touch it, pressure imbalance will occur, and the cell fluid in the lower part will increase, causing the leaves to close tightly, making it look as if it is shy.

2. It is native to South America, where it often encounters strong winds and heavy rains. When rain falls on its leaves, the petioles will begin to droop and the leaves will close. This is actually to avoid it from getting hurt, which can be said to be self-protection.

2. Precautions

During the maintenance period, do not always touch its leaves, because after touching the leaves, it will close tightly and it will take about 5-10 minutes to recover. If you keep touching it, the thin-walled cells inside the pulvinus will be lost and may not be replenished in a short period of time. When you touch it again, it will not be shy and it will feel as if it is a little wilted.
